20130217839 | GRAFTED POLY(ARYLSULFONE) AND A PROCESS FOR GRAFTING A POLY(ARYLSULFONE) - The invention relates to a poly(arylsulfone), the poly(arylsulfone) having an aryl group grafted with a covalently attached substituent of the Formula (I): The invention also relates to a process for grafting a poly(arylsulfone), in the presence of an enzyme, for the preparation of said grafted poly(arylsulfone). The poly(arylsulfone) according to the invention shows beneficial properties for application in a membrane. The invention therefore further relates to a membrane comprising a poly(arylsulfone) according to the invention, and to the use of a poly(arylsulfone) according to the invention in a separation process. In addition, the invention relates to a polymer blend and a copolymer comprising a grafted poly(arylsulfone) according to the invention, and to a membrane comprising such polymer blend or copolymer. | 08-22-2013 |
20120267326 | APPARATUS AND PROCESS FOR THE SEPARATION OF A PARTICULATE MATTER FROM A FLUID - The invention relates to an apparatus and a process for the treatment of an incoming fluid, comprising: a bottom part connecting a common feed stream to individual membrane filter modules through a tailor made connecting piece; a top part connecting individual membrane filter modules to a common retentate stream through a tailor made connecting piece. According to the invention the apparatus is assembled out of tailor-made parts with the object to reduce material costs and labor costs, and the part are made such that footprint of the contraption is minimized Furthermore, more, the individual parts form a sub-unit with such dimensions that multiple sub-units can be combined into one main unit, without the need to execute any alterations to the sub-units in terms of sizing, by which means modularity and scalability is introduced into the main units. | 10-25-2012 |
